Ginger alleviates mechanical hypersensitivity and anxio-depressive behavior in rats with diabetic neuropathy through beneficial actions on gut microbiome composition, mitochondria, and neuroimmune cells of colon and spinal cord. Nutr Res 2024; 124:73-84. [PMID: 38402829 DOI: 10.1016/j.nutres.2024.01.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 01/25/2024] [Accepted: 01/25/2024] [Indexed: 02/27/2024]
Abstract
The relationship among gut microbiota, mitochondrial dysfunction/neuroinflammation, and diabetic neuropathic pain (DNP) has received increased attention. Ginger has antidiabetic and analgesic effects because of its anti-inflammatory property. We examined the effects of gingerols-enriched ginger (GEG) supplementation on pain-associated behaviors, gut microbiome composition, and mitochondrial function and neuroinflammation of colon and spinal cord in DNP rats. Thirty-three male rats were randomly divided into 3 groups: control group, DNP group (high-fat diet plus single dose of streptozotocin at 35 mg/kg body weight, and GEG group (DNP+GEG at 0.75% in the diet for 8 weeks). Von Frey and open field tests were used to assess pain sensitivity and anxio-depressive behaviors, respectively. Colon and spinal cord were collected for gene expression analysis. 16S rRNA gene sequencing was done from cecal samples and microbiome data analysis was performed using QIIME 2. GEG supplementation mitigated mechanical hypersensitivity and anxio-depressive behavior in DNP animals. GEG supplementation suppressed the dynamin-related protein 1 protein expression (colon) and gene expression (spinal cord), astrocytic marker GFAP gene expression (colon and spinal cord), and tumor necrosis factor-α gene expression (colon, P < .05; spinal cord, P = .0974) in DNP rats. GEG supplementation increased microglia/macrophage marker CD11b gene expression in colon and spinal cord of DNP rats. GEG treatment increased abundance of Acinetobacter, Azospirillum, Colidextribacter, and Fournierella but decreased abundance of Muribaculum intestinale in cecal feces of rats. This study demonstrates that GEG supplementation decreased pain, anxio-depression, and neuroimmune cells, and improved the composition of gut microbiomes and mitochondrial function in rats with diabetic neuropathy.

Pinostrobin, a dietary bioflavonoid exerts antioxidant, anti-inflammatory, and anti-apoptotic protective effects against methotrexate-induced ovarian toxicity in rats. Tissue Cell 2023; 85:102254. [PMID: 37866152 DOI: 10.1016/j.tice.2023.102254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 10/02/2023] [Accepted: 10/19/2023] [Indexed: 10/24/2023]
Abstract
This study investigated the protective activities of pinostrobin (PIN) against methotrexate (MTX)-induced ovarian toxicity. Female rats were administered with PIN (50 mg/kg) for 4 weeks, while MTX was administered from weeks 2-4 of PIN treatment. Serum hormonal profiles, ovarian oxidative stress, inflammatory and apoptotic biomarkers as well as ovarian histomorphometry were evaluated. MTX administration elicited profound deficit in serum progesterone and estrogen (E2) levels, while luteinizing hormone (LH) and follicle stimulating hormone (FSH) were significantly increased. Additionally, MTX administration was associated with significant increases in ovarian malondialdehyde, nitric oxide, NF-кB, TNF-α, IL-6, IL-1β, iNOS and caspase-3 activity, as well as notable reduction in the activities of glutathione peroxidase, catalase and superoxide dismutase as well as the level of glutathione. Whereas, treatment with PIN significantly decreased serum levels of FSH and LH, as well as ovarian levels of NO, MDA, caspase 3, NF-κB, IL-1β, IL-6, TNF-α and iNOS. PIN also significantly upregulated GSH, GPx, CAT and SOD in the ovarian tissues as well as increased serum E2 and progesterone levels compared to the MTX group. Furthermore, PIN significantly restored altered ovarian histoarchitecture in the treated group. These findings suggests that PIN exerts protective effects against MTX-triggered ovarian damages.

Abstract
This study evaluated the cardioprotective properties of Boesenbergia rotunda extract (BrE) against doxorubicin (DOX) induced cardiotoxicity. Rats received oral gavage of BrE for 28 days and DOX (5 mg/kg/week for 3 weeks). Thereafter the animals were sacrificed, blood and cardiac samples were collected for biochemical, histological and immunohistochemical analyses. The results indicated that BrE attenuated DOX triggered body and cardiac weight loss and prevented against cardiac injury by mitigating histopathological alterations in cardiac tissues as well as serum cardiac function enzymes. BrE significantly reduced serum levels of aspartate transaminase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), troponin T (TnT) and creatine kinase-MB (CK-MB) in DOX-treated rats. Furthermore, BrE alleviated cardiotoxicity by reducing DOX instigated oxidative stress and potentiating the level of glutathione, as well as the activities superoxide dismutase and catalase in cardiac tissues. In addition, BrE significantly decreased the characteristic indices of DOX-induced cardiac inflammation and apoptosis. Immuno-histochemical analysis revealed that BrE decreased the stain intensity of p53 and myeloperoxidase (MPO) proteins compared to the DXB alone group. In conclusion, our results indicated that BrE modulated oxidative stress, inflammation and apoptosis to attenuate DOX-induced cardiac damage.

Abstract
Purpose Rheumatoid arthritis (RA) is a chronic autoimmune disease with severe inflammatory responses. Dehydrozingerone (DHZ) is a potent bioactive compound found in the rhizomes of Zingiber officinale, and it has been reported as an excellent anti-inflammatory and antioxidant agent. This study evaluated the anti-arthritic effects of DHZ in complete Freund’s adjuvant (CFA)-induced arthritis. Methods CFA administered rats were intragastrically treated with DHZ (100 mg/kg) for 28 days, and arthritis severity was assessed via body weight, arthritic score, paw edema and hyperalgesia. Serum inflammation biomarkers, oxidative stress markers, inflammatory cytokines and liver function enzymes were evaluated. Results The results indicated that DHZ significantly ameliorated arthritis severity as shown by reduced arthritic score, thymus and spleen indexes, paw circumference, paw withdrawal threshold and latency as well as increased body weight gain. Furthermore, DHZ treatment persuasively reduced serum levels of alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT), rheumatoid factor (RF), C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-1β and 6 (IL-1β and IL-6), malondialdehyde (MDA), vascular endothelial growth factor (VEGF) and transforming growth factor β (TGF-β). In addition, DHZ observably increased serum superoxide dismutase (SOD) and glutathione (GSH) levels in treated rats. Conclusion These findings suggest that DHZ possesses anti-RA effect properties via modulating the inflammatory responses and oxidative stress.

Ameliorative potentials of the ethanolic extract from Lycium chinense leaf extract against diabetic cardiomyopathy. Insight into oxido-inflammatory and apoptosis modulation. Biomed Pharmacother 2022; 154:113583. [PMID: 35994819 DOI: 10.1016/j.biopha.2022.113583] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 08/16/2022] [Accepted: 08/17/2022] [Indexed: 02/06/2023] Open
Abstract
The prevalence of cardiovascular complications in diabetes has become one of the major cause of diabetes related morbidity/mortality. The onset and progression of diabetic cardiomyopathy (DCM) has been majorly linked to lipid alterations, oxidative stress, inflammation and apoptosis. This present study investigated the cardioprotective role of Lycium chinense leaf extract (LCME) in fructose/streptozotocin induced diabetic rats. Diabetic animals were orally gavaged with LCME (100 and 400 mg/kg) for five weeks. The results indicated that diabetic rats showed increased blood glucose concentration, serum cardiac function markers (troponin T, creatine kinase-MB, aspartate aminotransferase and lactate dehydrogenase) and lipid profile (triglycerides and cholesterol). In addition, the cardiac tissues of diabetic rats showed increased levels of nuclear factor-κB (NF-κB), tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL 1β), interleukin 6 (IL-6), caspase-3 and malondialdehyde as well as significantly reduced activities of catalase, superoxide dismutase, reduced glutathione and glutathione peroxidase. LCME significantly ameliorated hyperglycemia and markedly decreased serum concentrations of troponin T, creatine kinase-MB, aspartate aminotransferase and lactate dehydrogenase, triglycerides and cholesterol. Furthermore, LCME notably suppressed cardiac oxido-inflammatory mediators and boosted cardiac antioxidant defense. Histopathologically, LCME restored cardiac structural alterations and also suppressed the immunohistochemical expression of collagen IV, smooth muscle alpha-actin (α-SMA) and p53, while Bcl2 expression was significantly increased. In conclusion, our result indicated that LCME protected against diabetic cardiomyopathy suppressing oxidative stress, inflammation, apoptosis and fibrosis.

Diabetes Metab Syndr Obes 2022; 15:1819-1829. [PMID: 35733641 PMCID: PMC9207258 DOI: 10.2147/dmso.s366609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Accepted: 05/25/2022] [Indexed: 11/23/2022] Open
Abstract
PURPOSE Research on plant-based formulations has drawn considerable attention in the management of diabetic neuropathy (DN) for having lesser side effects than the synthetic counterparts. Here, we have investigated for the first time the therapeutic effects of a standardized Piper nigrum L., (black pepper) seed extract, ViphyllinTM in mitigating hyperglycemia and neuropathic pain of type 2 diabetes model rats. METHODS Type 2 diabetes was induced in male Wistar rats using high fat diet and a single dose of streptozotocin (60 mg/kg i.p.). The diabetic rats were orally administered with Viphyllin containing not less than 30% β-caryophyllene (BCP), at 25 mg, 50 mg and 100 mg/kg/day doses for 6 weeks. Changes in body weight, fasting blood glucose (FBG), glucose tolerance, and blood biochemical parameters were measured. The nociceptive response to thermal stimulus (tail flick test) and sciatic nerve conduction velocity (NCV) were recorded at the end of study. RESULTS Viphyllin treatment markedly improved the body weight and glucose tolerance in diabetic rats. Also, the extract could significantly reduce the diabetes-induced elevation in FBG, liver and kidney indices. Further, Viphyllin dose-dependently increased the nociception latency in tail flick test compared to untreated diabetic rats (p<0.05). Viphyllin at 100 mg/kg significantly increased the NCV (44.12±1.91*** m/s vs diabetic control 25.80±1.88 m/s). The antioxidant enzyme activities in sciatic nerve tissue were considerably increased in Viphyllin-treated groups compared to diabetic control. A 6-week treatment with Viphyllin markedly reversed the pathological manifestations of diabetes in vital organs such as liver, kidney and pancreas. CONCLUSION The study concludes that Viphyllin exerts antidiabetic effects and improves nerve conduction to mitigate neuropathic pain.
